Is "marine epoxy" any different than regular epoxy?

Is there anything special about "marine epoxy". I'm not talking about epoxy for water tanks or to cure underwater. Just an epoxy for gluing/sealing stuff on a boat -- is there any reason to pay for...

Voltage drop solar controller to batteries

What % voltage drop should I be aiming for when sizing the wire gauge between mppt controller and batteries?

400 watts of panels. About 8-10ft from controller to 12v bank.

Putting the maximum...

Re: A/C from battery solar (actually realistic scenario?)

Surprised nobody with a big array on a fancy catamaran hasn't chimed in on this. I've read some posts on here by some people with massive lithium banks.

Re: 5-10hp 2-stroke vs 4-stroke

I actually have a 5hp Lehr that came with my trawler. I have been meaning to sell it for 2 years. All I see is disadvantages with propane outboards. To it's credit, it does start right up even though...

Re: 5-10hp 2-stroke vs 4-stroke

It get's rough where I anchor. I need something with at least enough power to get the bow up...but riding on top of waves on plane would be ideal.

I see Saturn sells a 11ft inflstable catamaran...

Looks like absolutely no consensus. Thanks for the input though!

5-10hp 2-stroke vs 4-stroke

I know nothing about small outboards (my tender is a 14ft fiberglass skiff with a 60hp). My gf moved on my boat and is gonna start back working soon. I want to get a little auxiliary dinghy for her...

Re: A/C from battery solar (actually realistic scenario?)

I see you are in England...I don't think you understand Miami summer. Every single day is about 90-95. It's EXTREMELY HUMID. The breeze usually dies off to nothing at night and the temps only drop a...

Re: A/C from battery solar (actually realistic scenario?)

I have survived 2 Miami summers without A/C. It can be done, but your life is run by the heat EVERY SINGLE DAY from June thru Sept. Sleep hot, wake up hot, then don't wanna do a damn thing all day so...

Re: A/C from battery solar (actually realistic scenario?)

My generator is quiet...and I anchor where there are no other boats, so there's nobody to complain anyway.

A/C from battery solar (actually realistic scenario?)

My trawler already has 500w solar on aft hardtop. I have space for 1200w more on my flybridge hardtop (that I've been itching to fill).

I just installed 860ah of new lead acid gc batteries, but i...

120v Chest Freezers

I'm planning to buy a cheap domestic 120v chest freezer in either 5 or 7 cu ft.

1)Does anybody have experience running one of these off a 1000w inverter -- is it enough for compressor startup?...

Re: Solar Controller for 1200 watts

Yes trawler. I've studied any potential shading and by the time the radar can cast a shadow, the sun is basically setting.

Re: Solar Controller for 1200 watts

My new bank will be 900ah lead acid. Actually i will have 1700w (because I already have 500w). Sure it's overkill for a sunny day, but not for a cloudy day. It's a 1 time cost for the panels, and I...

Re: Wire gauge from battery bank to 12v panel?

I'll probably add a 120v chest freezer, but that obviously is irrelevant. My electroscan is high amperage, but that's also direct wired with it's own breaker. I can't possibly think of any large...

Re: Wire gauge from battery bank to 12v panel?

There are separate wires for the engines, generator, inverter. This is strictly for the 12v panel.

Re: Solar Controller for 1200 watts

With a 150v/100a controller, i could series parallel 2 groups of 600w. It would be approx 120v/5a each. At that voltage I could use #16 wire from panels to controller. It would just be controller to...
